Why Global - Our Advantage

The Global Advantage: Knowledge & Experience, Highest Technology Capabilities, and Innovative Culture

 

Knowledge and Experience

The proven track record of our management team has been instrumental in attracting some of the most successful and experienced industry professionals to Global Geophysical. The original incarnation of Global Geophysical grew from 3 to over 325 employees in its first year of operation, and our goal is to meet or exceed that growth rate with the new company. We have already assembled a world-class team of industry leaders that have extensive experience operating in the most challenging environments all around the globe. Global employees have hundreds of years of cumulative experience working seismic operations in over 100 countries and in all types of terrain including mountains, deserts, arctic environments, urban centers, swamps, marshes, rivers, lakes, bays, and shallow marine environments from 0-150 meter water depths.
 

Geoscience Knowledge and Capital

 

Acquisition Solutions:
Global offers high density, Reservoir Grade 3D (RG3D®) seismic solutions for exploration and reservoir management.

• RG3D® products offer increased spatial resolution and improved signal-to-noise ratio for enhanced imaging of geologic structures.
• A survey acquired with RG3D® technology offers source and receiver density disproportionately greater than the incremental cost over a conventional 3D survey.
• Global’s geophysicists are also experts in crew operations, project management and logistics, thereby optimizing survey efficiency and crew productivity.

 

Processing & Imaging Solutions:
Our geoscience services partner, Z-Terra, offers industry leading processing technologies to its clients including: Wave Equation Pre stack Time Migration, 6-D Interpolation, Diffraction Imaging, Horizontal Transverse Isotropic PSTM, Gaussian Beam PSDM, Wave Equation PSDM, Fault Constrained Tomography, Beam Tomography, RTM, FWI and 3D Seamless Merge.

Additionally, the company offers value added services such as partial or full interpretation studies, regional and prospect seismic mapping, integration of seismic and potential field data, correlation of seismic and well results, and if needed, second opinions on complicated drilling prospects utilizing our in-house experience and industry recognized exploration consultants.  

 

Highest Technology and Equipment

The cornerstone of Global Geophysical's technology advantage is the NuSeis Nodal seismic system. NuSeis offers unique advantages compared to other nodal systems:

• NuSeis EARTHGRIP^™ coupling is extraordinary and yields higher signal to noise ratio data.
• NuSeis "Stealth Deployment" enables you to insert the node below the surface of the ground to avoid social disturbance, theft, and obtain the quietest deployment possible even in an urban settings.  Drive the spread, walk it, or fly it with a drone to capture the BLE-transmitted QC data from nodes underground.
• NuSeis transformability allows you to choose the best form factor for your upcoming project, providing you with the best operating performance and the best data quality for each environment and surface condition.
• NuSeis 1C nodes are well established globally, having worked in 15 countries over the last 8 years in all environments.
• NuSeis 2C node (hydrophone+geophone) development for shallow marine and transition zones is complete, and we are launching a 120,000 channel 2C crew in Q1 2024 for a world class deep gas plus carbon sequestration project.
• ​NuSeis 3C nodes are recording high quality data on the Mona Loa Volcano in Hawaii, on numerous engineering and natural earth seismicity programs, as well as induced seismicity projects globally.
• NuSeis 4C nodes are engineered and we are building a 5,000-node NRU OB4C asset base that will deploy in the Gulf of Mexico in Q1 2024.​

Data Acquisition

 

• RG3D

Reservoir Grade 3D: RG3D®

Global Geophysical provides Reservoir Grade Three Dimensional (RG3D®) seismic acquisition services. The seismic data that we provide is processed and used to create highly accurate images of the earth’s subsurface. Exploration and production companies use these images to locate potential oil & gas reserves based upon the geology observed.

High-density 3D Seismic Data

Global Geophysical offers exceptionally high trace density 3D seismic data sets to image increasingly complex structural and stratigraphic details within the geologic objectives. The benefits of high density 3D data include:

• Order of magnitude greater trace density providing improved signal-to-noise ratio
• Seismic datasets that provide longer shelf life throughout the G&G cycle of the field
• Unparalleled P wave information with excellent offset sampling at all azimuths for pre-stack analysis (AVA, AVO)
• Enhanced detailed images of the most challenging reservoirs

 

 

 

• Land

Land Acquisition Solutions Worldwide

With access to over 200,000 Nuseis NRU 1 single channel land nodes Global Geophysical Services can provide small 2D crews to large 3D crews achieving in excess of five million traces/km2, giving true value for our customers.
 

With our fleet of vibrators ranging from 62,000 to 80,000 pounds and state of the art source controllers we can deploy the most advanced vibroseis technology including:

• HFVS
• Offset Separated Simultaneous (OSS) seismic recording and slip-sweep
• ISS
• DSS

With our patented LandFlex vibrator track system we can convert our standard wheeled vibrators to track system allowing lower ground pressure and greater access in many terrains. This technology reduces line clearance costs, reduces environmental impact and overall program costs.
 

Total Operation Solutions: Global Geophysical Services provides total operation solutions, including:

• Comprehensive Program design
• In-house permitting
• Project planning
• Real-time kinematic, inertial and conventional surveying
• Shot-hole drilling and dynamite operations

 

 

 

 

• Transition Zone & Marine

Transition Zone and Marine Acquisition Solutions

Global Geophysical Services provides experienced worldwide ocean bottom nodal operations, through the transition zone and across the sea floor.

Our Marine Expertise

Marine Innovation: We provide innovative high-density, long-offset, rich-azimuth survey designs with superior subsurface illumination. We offer an unmatched range of receiver node configurations (1C, 2C, 3C, and 4C) along with innovative anchoring and seafloor coupling solutions to ensure the highest quality data in all transition zone and shallow marine environments.

State-of-the-art fleet: Our fleet is the industry’s most advanced fleet of specialized recording, airgun source and node handling vessels.

Seamless Land-to-Marine: With the latest technology, we acquire seamless surveys from land through the transition zone, and into shallow water.

 

 

 

• Marine Operations

Transition Zone and Ocean Bottom Solutions Worldwide

With access to over 80,000 NRU-KCK2 2 channel TZ nodes and 50,000 NRU OB4 4 channel OBN nodes Global Geophysical Services can provide a truly seamless data set from Onshore – Transition (0 -15 meters water depth) – Ocean Bottom Node (15 - 200 meters water depth) giving true value for our customers.

 The acquisition of Transition and Ocean Bottom Nodal surveys various source types are required. Global Geophysical Services can deploy explosives as an acoustic source in the shallowest depths, shallow draft source vessels in shallow to medium depths and tuned airgun arrays in the deeper waters.

 Through our extensive experience and planning we understand the requirements of Node deployment in Transition and Ocean Bottom Nodal surveys and the need for multiple deployment vessels. These vessels and deployment methods vary from small shallow draft manual handling vessels to larger, specialised node handling vessels configured to ensure safe and efficient node deployment and retrieval even in heavily congested marine environments.
